A novel model for evaluating therapies targeting human tumor vasculature and human cancer stem-like cells.
Burgos-Ojeda D, McLean K, Bai S, Pulaski H, Gong Y, Silva I, Skorecki K, Tzukerman M, Buckanovich RJ (2013) A novel model for evaluating therapies targeting human tumor vasculature and human cancer stem-like cells. Cancer Res 73(12):3555-3565. doi: 10.1158/0008-5472.CAN-12-2845
Objective: To evaluate tumor vascular markers (TVM) expression in a human embryonic stem cell–derived teratoma (hESCT) tumor model previously shown to have human vessels.
Summary: The model tested represents a useful tool to test anti-human TVM therapy and evaluate in vivo human CSC tumor biology.
Usage: In vitro – Anti-THY1-SAP (biotinylated Anti-THY1 mixed equimolar with Streptavidin-ZAP) was incubated with mesenchymal stem cells (MSC); resulting in statistically significant MSC death. In vivo – Anti-THY1-SAP or control (Rat IgG-SAP) was administered intravenously. Treated ovarian tumors showed delayed growth and significant reduction in central tumor viability.

P2Y1 receptors expressed by C1 neurons determine peripheral chemoreceptor modulation of breathing, sympathetic activity, and blood pressure.
Wenker IC, Sobrinho CR, Takakura AC, Mulkey DK, Moreira TS (2013) P2Y1 receptors expressed by C1 neurons determine peripheral chemoreceptor modulation of breathing, sympathetic activity, and blood pressure. Hypertension 62(2):263-273. doi: 10.1161/HYPERTENSIONAHA.113.01487
Summary: Peripheral chemoreceptor activation response is mediated by catecholaminergic C1 cells in the rostral ventrolateral medulla (RVLM). The authors investigated the molecular mechanisms linking this drive to increased sympathetic activity and hypertension through a variety of methods, including lesioning C1 cells in the RVLM. Rats received 4.2-ng bilateral injections of Anti-DBH-SAP (Cat. #IT-03) into the RVLM. Comparison of lesioned animals to controls demonstrated that P2Y1 receptors on C1 cells in the RVLM are key components in the regulation of breathing, sympathetic nerve activity, and blood pressure.

A small molecule angiotensin II type 2 receptor (AT₂R) antagonist produces analgesia in a rat model of neuropathic pain by inhibition of p38 mitogen-activated protein kinase (MAPK) and p44/p42 MAPK activation in the dorsal root ganglia
Smith MT, Woodruff TM, Wyse BD, Muralidharan A, Walther T (2013) A small molecule angiotensin II type 2 receptor (AT₂R) antagonist produces analgesia in a rat model of neuropathic pain by inhibition of p38 mitogen-activated protein kinase (MAPK) and p44/p42 MAPK activation in the dorsal root ganglia. Pain Med 14(10):1557-1568. doi: 10.1111/pme.12157 PMID: 23742186
Objective: To elucidate the mechanism through which EMA300, a small molecule antagonist of the angiotensin II type 2 receptor (AT2R) with >1,000-fold selectivity over the angiotensin II type 1 receptor, produces analgesia in a rodent model of neuropathic pain.
Summary: Augmented angiotensin II/AT2R signaling in the DRGs of CCI rats is attenuated by EMA300 to block p38 MAPK and p44/p42 MAPK activation, a mechanism with clinical validity for alleviating neuropathic pain.
Usage: Immunostaining (1:250), rat DRG sections

Summary: Rats received 168 ng of 192-IgG-SAP (Cat. #IT-01) into the medial septum and induction of c-Fos expression in response to either familiar or novel stimuli was measured.

Neurotrophin receptor p75 mediates the uptake of the amyloid beta (Abeta) peptide, guiding it to lysosomes for degradation in basal forebrain cholinergic neurons.
Ovsepian SV, Antyborzec I, O’Leary VB, Zaborszky L, Herms J, Oliver Dolly J (2013) Neurotrophin receptor p75 mediates the uptake of the amyloid beta (Abeta) peptide, guiding it to lysosomes for degradation in basal forebrain cholinergic neurons. Brain Struct Funct 219(5):1527-1541. doi: 10.1007/s00429-013-0583-x PMID: 23716278
Summary: Accumulation of β-amyloid in the brain is considered one of the main causes of Alzheimer’s disease. The increase in β-amyloid is accompanied by a reduction in levels of the high affinity nerve growth factor receptor (trkA) and cognitive impairment. The authors looked at levels of the low affinity nerve growth factor receptor (p75) that do not decline. Using a 0.8-μg injection of 192-Cy3 (Cat. #FL-01) into the medial prefrontal cortex of rats the authors assessed the transport of p75 and β-amyloid by microscopy. The results indicate that the primary destinations of both p75 and β-amyloid were the late endosome and lysosome.

Cholinergic basal forebrain structures are involved in the mediation of the arousal effect of noradrenaline.
Lelkes Z, Porkka-Heiskanen T, Stenberg D (2013) Cholinergic basal forebrain structures are involved in the mediation of the arousal effect of noradrenaline. J Sleep Res 22(6):721-726. doi: 10.1111/jsr.12061
Summary: Wakefulness is enhanced by the injection of noradrenaline into the basal forebrain, but it has not been clear whether cholinergic or non-cholinergic neurons are involved. 230 ng of 192-IgG-SAP (Cat. #IT-01) was administered to the horizontal diagonal band/substantia innominata/ magnocellular preoptic nucleus of rats. Upon treatment with methoxamine, lesioned animals lost the non-REM sleep-suppressing effect, but the REM sleep-suppressing effect remained intact.

The cells and circuitry for itch responses in mice.
Mishra SK, Hoon MA (2013) The cells and circuitry for itch responses in mice. Science 340(6135):968-971. doi: 10.1126/science.1233765
Summary: Although previous work implicated neurons expressing the GRP (gastrin-releasing peptide) receptor were in the pruritic, or itch pathway, transgenic mice lacking natriuretic polypeptide b (Nppb) were almost completely insensitive to itch. Using the custom conjugate Nppb-SAP (Cat. #IT-69), the authors eliminated itch in response to a wide range of pruritic substances in normal mice through the administration of 5 μg of conjugate into the intrathecal space. Even after this lesion, the scratching response to intrathecal GRP was not changed, indicating that the role of GRP is at a later stage than previously hypothesized.

Collagen-like cell-penetrating peptides
Yamazaki CM, Nakase I, Endo H, Kishimoto S, Mashiyama Y, Masuda R, Futaki S, Koide T (2013) Collagen-like cell-penetrating peptides. Angew Chem Int Ed Engl 52(21):5497-5500. doi: 10.1002/anie.201301266
Objective: To overcome drawbacks of cell-penetrating peptide (CPP)-conjugated forms, namely instability against attack by proteases, and binding to serum proteins that lowers the availability of the CPP to target cells.
Summary: Complexes were prepared by combining biotinylated CPPs with Streptavidin-ZAP to evaluate the impact of utilizing a rigid collagen-like triple-helical scaffold to improve CPP performance. There was low adsorption onto serum proteins and triple-helical CPPs are extremely stable in animal serum. Such unique properties are expected to be advantageous to long-term applications in cell culture systems and to in vivo drug delivery.
Usage: Biotinylated CPPs were interacted with Streptavidin-ZAP (SA-ZAP); IT-27: Streptavidin-ZAP

State-dependent contribution of the hyperpolarization-activated na+/k+ and persistent na+ currents to respiratory rhythmogenesis in vivo.
Montandon G, Horner RL (2013) State-dependent contribution of the hyperpolarization-activated na+/k+ and persistent na+ currents to respiratory rhythmogenesis in vivo. J Neurosci 33(20):8716-8728. doi: 10.1523/JNEUROSCI.5066-12.2013 PMID: 23678115
Summary: The hyperpolarization-activated cation current in the preBötzinger complex (preBötC) was identified as a critical component of respiratory rhythm. An anti-neurokinin 1 receptor antibody (Cat. #AB-N04 replaced by Cat. #AB-N33AP) at a 1:1000 dilution was used to identify preBötC neurons in the brainstem.
